Chapter 1 Product Outline
1.1 Outline
JIEXIANG 4 in 1 Mux-scrambling QAM modulator is a cost effective
integrated 4 in 1 QAM modulator supporting multiplexing and scrambling.
This device supports maximum 16 ASI input, after 4 multiplexer and 4
scrambler process, then gives 4 carriers output (4 adjacent frequency
output by 1 RF port). It’s ideal for processing ASI input data from different
devices and giving RF output by only one device. With its powerful function,
it can reduce the operator business cost effectively.

carefully check before running.
3.2.3 Grounding Requirement
All function modules’ good grounding designs are the base of reliability
and stability of device. Also, they are the most important guarantee of
lightning arresting and interference rejection. Therefore, system must
follow this rule:
1. Coaxial cable’s outer conductor and isolation layer should keep sound
electric conducting with the metal housing of device.
2. Grounding conductor must adopt copper conductor in order to reduce
high frequency impedance, and the grounding wire must be as thick and
short as possible.
3. The 2 terminals of grounding wire must make sure for well electric
conducting, and process for antirust.
4. It is prohibited that users use other devices as part of grounding wire’s
electric circuit
3.2.3.1 Frame Grounding
All the machine frames should connect to protective copper strip. The
grounding wire should be as short as possible and avoid circling. The
section of the conjunction between grounding wire and grounding strip
should be equal or greater than 25mm2.
3.2.3.2 Device Grounding
User can connect the device’s grounding rod to frame’s grounding strip
with copper wire.
3.2.4 Wires’ Connection
The power supply outlet is located at the right of rear panel, and the power
switch is just above it. The protective grounding wire connective screw is
located at the down-right side of power supply outlet.
1. Connecting power cord

2. User can insert one end into power supply outlet, while insert the other
end to AC power.
3. Connecting grounding wire
4. When the device solely connects to protective ground, it should adopt
independent way, say, sharing the same ground with other devices. When
the device adopts united way, the grounding resistance should be less
than 1Ω
Caution: Before connecting power cord to 4 in 1 Mux-Scrambling
QAM, user should set the power switch to “OFF”.
3.2.4.1 Signal wire connection of ASI IN
The data input cable of 4 in 1 Mux-Scrambling QAM is ASI cable, while the
output cable is the normal 75 Ω coaxial cable. The illustration is as below:

Note: The more advanced QAM constellation mode, the higher
transmission efficiency and TS coding rate which the device can transport
at the same symbol rate. Accordingly, with the TS coding rate increasing,
the signals’ anti-jamming capability will become weaker. Hence, those
wired network currently in effect usually adopt QAM modulation mode no
exceeding 64QAM.
What needs to be pointed out is, the effective coding rate this modulator
can transport is limitary when the device works as different constellations
and symbol rates.
User can refer to the formula as below:
Max_input_bitrate = Symb_rate*qam_bits*188/204
Max input bit rate: the maximum effective inputting coding rate
Symb rate: the symbol rate
Qam_bits: the QAM bit when device works as current constellation (user
can refer to the following table when device works as 6.875Msps symbol
rate):

The symbol rate range is from 5.0~7.0 Msps in 1ksps step.
Note: When users choose 6M as the frequency point bandwidth, the
symbol rate should not exceed 5.217Msps;
When users choose 8M as the frequency point bandwidth, the symbol rate
should not exceed 6.956Msps.
4.3.2.5 Frequency point bandwidthAfter entering the submenu by pressing ENTER key, user can set the
bandwidth by moving the LEFT/RIGHT key and then repressing ENTER to
confirm.
There are two possible options: 6MHz and 8MHz.
Therefore, the frequency interval should be integral multiple of
6MHz/8MHz.
User can refer to the formula as below:
RF_BW=symb_rate*(1+roll_off)
RF_BW:Frequency bandwidth
Symb rate:Symbol rate
Roll off:Roll off factor(according to EN300429/ITU-T J.83A,the roll off
factor is 0.15)
As the formula shown, user should set the symbol rate no exceeding
5.214Msps/6.956Msps to ensure the bandwidth for each channel no more

In this interface, user can input and check the source of PIDs in the first box,
the value of PIDs source in the second box and value of outputting PIDs which
has been bypassed. Clicking “OK”, user can return to the interface shown as
below and proceed to other operations through buttons listed beside.
5.3.1.4 Parameters
User can set the output parameters in this interface, the display shows as
below.
TS ID: the output 1 TS ID number.
SDT: SDT table output or not.
Original Network ID: Set the original network ID number.
NIT insertion: “Enable” means the device will send the NIT
table by itself and “Disable” means the NIT table cannot be sent out.
Pass through/Multiplexing: “Pass through” will enable all the
inputting programs be sent out while “Multiplexing” will just enable the
programs which had been multiplexed be sent out.
Note: usually if there is EPG information with the SDT and NIT table, the
Device SDT and NIT can be set as Disable.

After checking the checkbox, the NIT editing menu is active. And also the
device will insert the EIT table into the output TS.
: It means to replace the NIT table when users select it, and
then users can edit the NIT table and output it.
and : These two buttons can trigger a window to
load/save the saved NIT table file from/to a file on local computer hard disk.
:Users can add the cable transmission descriptor in Add button.

Modulation standard: EN300 429/ITU-T J.83A/B/C
Constellation: 16QAM/32QAM/64QAM/128QAM/256QAM optional
Symbol Rate range: 5.0~7.0Msps, 1ksp step
Bandwidth:6M/8M optional
Start Freq: The RF output frequency range is from 48MHz to 1000MHz. Here
the start frequency means the centre frequency of TS output.
Therefore, user can only set the start frequency from 48MHz to 968MHz (if the
bandwidth is 8M) and from 48MHz to 976MHz (if the bandwidth is 6MHz).
Out gain: attenuation ranges -25dBm~6dBm,0.5dB stepping
Note: the start frequency discussed here means centre frequency. The 4
Carriers output is 4 adjacent channel RF output.

Making sure good ventilation for the heat-sink on the rear panel and other
heat-sink bores if necessary
Checking the input AC voltage within the power supply working range and
the connection is correct before switching on device
Checking the RF output level varies within tolerant range if it is necessary
Checking all signal cables have been properly connected
Frequently switching on/off device is prohibited; the interval between every
switching on/off must greater than 10 seconds.
Conditions need to unplug power cord
Power cord or socket damaged.
Any liquid flowed into device.
Any stuff causes circuit short
